Students should:
$understand how ideas about electronic configuration developed from: i the fact that atomic emission spectra provide evidence for the existence of quantum shells ii the fact that successive ionisation energies provide evidence for the existence of quantum shells and the group to which the element belongs iii the fact that the first ionisation energy of successive elements provides evidence for electron sub-shells$
